Colmac Coil receives patent on plate freezer innovation
The innovative design resolves deficiencies and helps ensure a safe environment for workers near the freezers.
Colmac Coil, Colville, Wash., and president Bruce Nelson received a new patent for its plate freezer innovations.
Traditional direct contact plate freezer designs produce common reoccurring deficiencies, which result in potential health hazards. To counteract the non-uniform distribution of liquid refrigerant in traditional plate freezers, increased levels of refrigerant are used. This creates a health hazard if the refrigerant leaks.
